设置Vulkan API时遇到问题

Question

我想在我的Linux Ubuntu 16.04计算机上设置Vulkan API，但是它不起作用。 我完全遵循了“入门”。

当我尝试运行vulkaninfo时，出现以下信息：

VULKAN INFO

Instance Extensions:

当我尝试启动多维数据集时，我得到以下信息：

cube: /home/adrian/vulkan/VulkanSDK/1.0.37.0/examples/cube.c:2789: demo_init_vk: Assertion `!err && gpu_count > 0' failed.
Abgebrochen (Speicherabzug geschrieben)

最后一条消息表示“已中止”，然后在括号中表示“核心已转储”

我正确设置了环境变量：

export PATH=$HOME/vulkan/VulkanSDK/1.0.37.0/x86_64/bin
export LD_LIBRARY_PATH=$HOME/vulkan/VulkanSDK/1.0.37.0/x86_64/lib
export VK_LAYER_PATH=$HOME/vulkan/VulkanSDK/1.0.37.0/x86_64/etc/explicit_layer.d

我有Nvidia Geforce GT 730，带有支持Vulkan的367.57驱动程序

谁能帮我？

Answer 1

作为Vulkan SDK的一部分，包含了Vulkan安装分析器（VIA）。 运行此工具以对安装进行全面分析。 如果您不了解输出，请在LunarXchange（vulkan.lunarg.com）上将VIA的输出作为问题提交，LunarG工程师将为您提供帮助。 您可以找到有关如何在SDK安装过程中运行VIA的文档，或在以下LunarXchange上查看它： https ://vulkan.lunarg.com/doc/sdk/1.0.37.0/windows/via.html

在linux发行版上，如果我安装了假/匀速驱动程序（例如，在禁用iGPU的情况下为Mesa Intel或在我的GPU仍不受支持的情况下为Mesa RADV），这就是我会发生的情况。
